I was so excited to get the the silicone practice skins. I really do love practicing the shapes, lines, and s patterns! However, The silicone was hard to get pigment into. I tried several different needles & pigments. I had to use more pressure than would realistically be used on a person, to get my practice work to barely show up. I also bought the silicone set with various skin tones, when you first intoduced them, and had the same difficulty & disappointment. I love all things Shay/Beauty Ink...
